MILK-COOLER.

SPECIFICATION forming part of Letters Patent No. 653,072, dated July 3,1900.

' Application filed January 30, 1900. serial NO- 3,310. (No model.)

To all whom, it may concern:

Be it known that LWILLIAM VOLNEY DEAN, a citizen of the United States,residing at Valley Mills, county of Bosque, State of Texas, haveinvented certain new and useful Improvements in Milk-Coolers, of whichthe following is a specification.

This invention relates to milk-coolers, and has for one of its objectsthe provision of a simple and inexpensive knockdown construction whichwill permit packing into compact form when desirable.

Another object is to provide a milk-cooler having adjustable shelves ofimproved construction, whereby milk pans or pails of different sizes canbe easily accommodated.

A further object of the invention is to provide a milk-cooler of thewater-evaporation capillary-feed type which will be strong, compact, andof large capacity and provided with improved means for draining,catching, and

retaining the water, holding the fabric, and

adjusting and securing the shelves.

Having the foregoing and other objects in View, the invention consistsof certain improved features and combinations set forth in detailhereinafter and recited in the appended claims.

In the accompanying drawings, Figure 1 is a perspective view with thefabric broken away to disclose the shelves and standards; Fig. 2, alongitudinal sectional viewtaken through one of the standards, and Fig.3 a detail view illustrating the manner of fastening the fabric.

There is a bottom tray 1, having legs 2 at its corners, and a pluggeddrain outlet 3, which is adapted to catch the water as it is fed ordrains downward. Inside this tray, at the cornersthereof, are hollowvertical stubstandards 4. Hollow main standards 5 have their lower endstelescoping over the stubstandards and resting on the bottom of the tray1.

A top tray 6 of somewhat smaller size than the bottom tray is provided,and it is equipped with hollow stub-standards 7 atits corners whichtelescope over the upper ends of the main standards 5 in such mannerthat the tops of the latter abut the bottom of said top tray.

Shelves 8 in the form of trays and of ap proximately the same size asthe top tray 6 are located one abovethe other between the top and bottomtrays. The number of these trays can be varied as found desirable.shelves have apertures 9 inside the four corners thereof, through whichthe standards 5. loosely pass, and the shelves are thus made adjustableup and down toany extent onsaid They are clamped or held in p'o-'standards. sition on the standards by set-screws 10,which pass throughthe sides of the shelf and bind The' on the standard. In the presentinstance I perfect circulation of air, I provide them with openings 12.The capillary-feed fabric 13 hangs from the top tray 6 into the bottomtray 1" and coin pletely surrounds the shelves. This fabric is connectedto the top and bottom trays in the manner shown in Fig. 3. The top edgeof the side of the tray is bent over at 14, and between this bentportion and the side of the tray are secured, preferably by soldering,one end of the prongs 15, over which the fabric is caught. These prongsconstitute a convenient means for properly securing the fabric and yetpermitting its ready removal.

A water pail or reservoir 16, having suitable supporting-legs, restswithin the top tray and is provided with a delivery faucet or cock 17for regulating the flow from the reservoir into the tray.

The device is used as follows: The pans or pails containing the milk tobe cooled are placed on the shelves, which have previously beenadjusted. The fabric is then placed in position and the faucet 1? openedto allow the water contained in the reservoir to feed into the top tray.The water in the tray will then feed up into the edge of the fabric anddown through it to the bottom tray by capillary attraction and willdrain into said bottom tray, from which it can be drawn off when desiredby removing the plug from the drain-outlet.

The evaporation of the water as it passes.

through the large area of exposed fabric is quite great and thesurrounding air is cooled thereby, resulting in a rapid cooling of .themi k.

'lhe'construction of the present invention is such that the standards,shelves, top tray, and pail can be taken apart very easily, thuspermitting packing of the device into compact form when desired, whilethe shelves can be adjusted to suit milk pails or pans of differentsizes, and the construction is both strong and capacious.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. In a milk-cooler, the combination with a bottom tray and' a top tray,both of which are provided with bent edges and prongs secured betweensaid bent edges and the tray itself, standards rising from the bottomtray and detachably connected to it and to the top tray, shelves securedto said standards, and a capillary-feed fabric having its upper andlower whereby the shelves can be adjusted on the standards, and providedwith setscrews which are threaded through the shelves and are adapted tobe screwed against the standards to bind thereon and clamp the shelvesthereto.

In testimony whereof I hereunto affix my signature in presence of twowitnesses.
